DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIG. 1 is a perspective view of an electronic device according to anembodiment of the invention. FIG. 2 is a partial perspective view of ahinge structure adopted by the electronic device of FIG. 1. Withreference to FIG. 1 and FIG. 2, in this embodiment, an electronic device50 includes two bodies 52 and 54 and a hinge structure 100. Theelectronic device 50 is, for example, a notebook computer, in which thebody 52 is an upper body having modules like a monitor, etc.; the body54 is a lower body having modules like a keyboard, a processing unit,etc.; the hinge structure 100 (shown in dashed lines in FIG. 1) isdisposed between the two bodies 52 and 54 (more preferably, hiddenbetween the two bodies 52 and 54) so that the two bodies 52 and 54 areadapted to rotate in relative to each other by the hinge structure 100for changing between a closed mode (the two bodies 52 and 54 are foldedinto one) and an open mode (the two bodies 52 and 54 are unfold to beseparated from each other), but the invention is not limited thereto.

Specifically, the hinge structure 100 includes a hinge cover 110 and twohinge assemblies 120. The hinge cover 110 is disposed between the twobodies 52 and 54, and the two hinge assemblies 120 are respectivelydisposed at two opposite sides of the hinge cover 110 so as to connectthe two bodies 52 and 54 together from the two opposite sides of thehinge cover 110. The two hinge assemblies 120 may adopt the same design,and may also adopt partially different or completely different designs.As illustrated in FIG. 2, one of the hinge assemblies 120 furtherincludes three hinge portions 130. Two of the three hinge portions 130(e.g., the hinge portions 130 at the left and the right sides)correspond to the body 52 (the corresponding portions are shown indashed lines in FIG. 1), and one of the three hinge portions 130 (e.g.,the hinge portion 130 at the middle) corresponds to the body 54 (thecorresponding portion is shown in dashed lines in FIG. 1). The threehinge portions 130 may adopt the same design, and may also adoptpartially different or completely different designs. However, the numberand the implementation of the hinge assemblies 120 and the hingeportions 130 adopted by the hinge structure 100 are not particularlylimited in the invention (i.e., the hinge structure 100 may have onlyone hinge assembly 120 or one hinge portion 130) and may be adjusted asneeded.

FIG. 3 is a partial perspective view of the hinge structure of FIG. 2.FIG. 4 is a partial exploded view of the hinge structure of FIG. 3.Referring to FIG. 2 to FIG. 4, FIG. 3 illustrates a perspective view ofthe hinge portion 130 at the middle of the hinge structure 100, and FIG.4 illustrates an exploded view of the hinge portion 130 at the middle.In this embodiment, each of the hinge portions 130 of the hingestructure 100 includes a torsion element 140, a bracket 150, a fixingelement 160 and a shaft 170. The torsion element 140 is disposed at thehinge cover 110 (as shown in dashed lines in FIG. 2) and has a firstthrough portion 142 and a connecting portion 144. The bracket 150 isdisposed at a side of the torsion element 140, fixed at one of the twobodies 52 and 54 (as shown in dashed lines in FIG. 1) and has a secondthrough portion 152 and a connecting portion 154. The fixing element 160is disposed between the torsion element 140 and the bracket 150 and hasa third through portion 162 and a fixing portion 164. The shaft 170 isdisposed at the hinge cover 110 and passed through the first throughportion 142, the second through portion 152 and the third throughportion 162 so that the first through portion 142, the second throughportion 152 and the third through portion 162 are arranged adjacent toeach other.

Specifically, in this embodiment, the first through portion 142 of thetorsion element 140 is in form of a tube shape having a stripe opening146 and sleeved on the shaft 170, and the connecting portion 144 of thetorsion element 140 is in form of a plate shape and fixed at the hingecover 110 (as shown in dashed lines in FIG. 2). In this way, the torsionelement 140 can rotate in relative to the shaft 170 through the firstthrough portion 142. Similarly, the second through portion 152 of thebracket 150 is in form of a tube shape having an stripe opening 156 andsleeved on the shaft 170, and the connecting portion 154 of the bracket150 is in form of a plate shape and fixed at one of the two bodies 52and 54 (as shown in dashed lines in FIG. 1). In this way, the bracket150 can rotate in relative to the shaft 170 through the second throughportion 152.

Further, in this embodiment, the fixing element 160 is fixed at one ofthe torsion element 140 and the bracket 150 (e.g., fixed at the torsionelement 140) by the fixing portion 164. More specifically, said one ofthe torsion element 140 and the bracket 150 (e.g., the torsion element140) has an engaging portion 148. The engaging portion 148 is disposedat the connecting portion 144 of the torsion element 140, and the fixingelement 160 is fixed at said one of the torsion element 140 and thebracket 150 (e.g., fixed at the torsion element 140) by the fixingportion 164 being engaged with the engaging portion 148. In this way,with the fixing relationship between the fixing element 164 and thetorsion element 140, when the torsion element 140 rotates in relative tothe shaft 170, the fixing element 160 driven by the torsion element 140may also rotate in relative to the shaft 170 through the third throughportion 162. That is to say, when said one of the two bodies 52 and 54that is fixed with the bracket 150 rotates in relative to the hingecover 110 and another one of the two bodies 52 and 54, said one of thetorsion element 140 and the bracket 150 (e.g., the torsion element 140)is adapted to rotate with the fixing element 160 in relative to anotherone of the torsion element 140 and the bracket 150 (e.g., the bracket150) through the shaft 170 as an axle center. In other words, when saidone of the torsion element 140 and the bracket 150 rotates in relativeto said another one of the torsion element 140 and the bracket 150through the shaft 170 as the axle center, said one of the torsionelement 140 and the bracket 150 also drives the fixing element 160 torotate in relative to said another one of the torsion element 140 andthe bracket 150 through the shaft 170 as the axle center.

More specifically, in this embodiment, the fixing element 160 includes aplurality of fixing plates 160 a and 160 b. The fixing plates 160 a and160 b has substantially similar sizes and designs and are disposedoverlapping each other. That is to say, each of the fixing plates 160 aand 160 b has the third through portion 162, the fixing portion 164 andan extending portion 166. The third through portion 162 corresponds tothe first through portion 142, and the extending portion 166 extendsoutwardly from the third through portion 162 and corresponds to theconnecting portion 144. Also, the fixing portion 164 is located on theextending portion 166 and corresponds to the engaging portion 148 sothat aforementioned portions of the fixing plates 160 a and 160 bcorrespond to each other and overlap with each other. Accordingly, thethird through portions 162 of the fixing plates 160 a and 160 b of thefixing element 160 are in from of a ring shape and disposed around theshaft 170, and each of the fixing portions 164 of the fixing plates 160a and 160 b of the fixing element 160 is an engaging opening and fixedat the torsion element 140. Further, the fixing element 160 has auniform thickness in an extending direction of the shaft 170 to stablyabut between the torsion element 140 and the bracket 150.

Nonetheless, although the fixing element 160 of this embodiment takesthe two fixing plates 160 a and 160 b fixed at the torsion element 140as an example, the fixing element 160 may also be formed by one fixingplate or three fixing plates formed overlapping each other in otherembodiments not shown. Alternatively, the fixing plates 160 a and 160 bmay also be connected and formed as one piece and fixed at one of thetorsion element 140 and the bracket 150 (e.g., the torsion element 140).That is to say, the fixing plates 160 a and 160 b may be in form aspring surrounding the shaft 170. In addition, although this embodimenttakes the engaging portion 148 disposed at the connecting portion 144 ofthe torsion element 140 and the fixing portion 164 disposed at theextending portion 166 as an example, the engaging portion 148 may bedisposed at the first through portion 142 of the torsion element 140 andthe fixing portion 164 may be disposed at the third through portion 162in other embodiments not shown so that the disposition of the extendingportion 166 may be omitted in such case. Furthermore, although thisembodiment takes the fixing element 160 fixed at the torsion element 140as an example, the fixing element 160 may also be fixed at the bracket150. That is to say, the engaging portion 148 is disposed at the bracket150 instead to be engaged with the fixing portion 164 of the fixingelement 160. The invention is not limited to aforesaid implementations.As can be seen, the number and the form of the fixing plates 160 a and160 b used as the fixing member 160 are not particularly limited in theinvention and may be adjusted as needed.

FIG. 5 is a partial exploded view of the hinge structure according toanother embodiment of the invention. With reference to FIG. 5, a majordifference between a hinge portion 130 c and the hinge portion 130described above is that the fixing element 160 adopted by the hingeportion 130 includes the fixing plates 160 a and 160 b whereas thefixing element 160 adopted by the hinge portion 130 c includes a fixingblock 160 c. More preferably, the fixing block 160 c served as thefixing element 160 has a uniform thickness in an extending direction ofthe shaft 170 to stably abut between the torsion element 140 and thebracket 150, but not limited thereto. In this case, the fixing block 160c has a third through portion 162 c, a fixing portion 164 c and anextending portion 166 c. Here, the third through portion 162 c is inform of a tube shape, sleeved on the shaft 170 and corresponds to thefirst through portion 142, and the extending portion 166 c extendsoutwardly from the third through portion 162 c and corresponds to theconnecting portion 144. Also, the fixing portion 164 c is located on theextending portion 166 c and corresponds to the engaging portion 148. Inaddition, the fixing portion 164 c may be the engaging opening or anengaging recess. That is to say, because the fixing element 160 of thisembodiment only adopts one fixing block 160 c, the fixing portion 164 cto be engaged with the engaging portion 148 may be a penetrated-throughopening or a non-penetrated-through recess as long as the engagingportion 148 may be engaged with the fixing portion 164 c. Nonetheless,in other embodiments not shown, the number of the fixed block 160 c mayalso be plural, and the invention is not limited thereto.

As can be seen from the above description, the form of the fixingelement 160 is not particularly limited in the invention so long as thefixing element 160 may abut between the torsion element 140 and thebracket 150 and may be fixed at one of the torsion element 140 and thebracket 150. However, the fixed block 160 c adopted by the fixingelement 160 may be manufactured by adopting a metal injection molding(MIM) process, and the fixing plates 160 a and 160 b adopted by thefixing element 160 may be manufactured by adopting a metal stampingtreatment process. Accordingly, because the fixing plates 160 a and 160b manufactured by adopting the metal stamping treatment process has alower cost than the fixed block 160 c manufactured by adopting the metalinjection molding process, the fixing element 160 that adopts the fixingplates 160 a and 160 b can reduce overall cost for the hinge structure100 and the electronic device 50. However, the invention is not limitedto the above, and the shape, the number, the assembly and themanufacturing method of the fixing element 160 may be adjusted asneeded.

FIG. 6 is a partial exploded view of the hinge structure according toyet another embodiment of the invention. With reference to FIG. 6, amajor difference between a hinge portion 130 d and the hinge portion 130described above is that the fixing element 160 adopted by the hingeportion 130 is disposed between the torsion element 140 and the bracket150 whereas the fixing element 160 adopted by the hinge portion 130 d isdisposed at another side of the torsion element 140 opposite to thebracket 150 (e.g., the left side of FIG. 6). The specific structure ofthe fixing element 160 includes the fixing plates 160 a and 160 bdescribed above, but may also be changed to the fixing element 160 c(i.e., the fixing block) used in the embodiment of FIG. 5 or other typesof fixing elements (e.g., one single fixing plate or multiple fixingplates connected and formed as one piece). Here, the fixing element 160is sleeved on the shaft 170 through the third through portion 162 andcorresponds to the first through portion 142, and the extending portion166 extends outwardly from the third through portion 162 and correspondsto the connecting portion 144. Also, the fixing portion 164 is locatedon the extending portion 166 and corresponds to the engaging portion 148located another side of the connecting portion 144 to fix the fixingelement 160 at the torsion element 140. Similarly, in other embodimentsnot shown, the fixing element 160 may also be disposed at another sideof the bracket 150 opposite to the torsion element 140 (e.g., the rightside of FIG. 6). In this case, the fixing element 160 is sleeved on theshaft 170 through the third through portion 162 and corresponds to thesecond through portion 152, and the engaging portion is disposed at thebracket 150 so that the fixing portion 164 can be fixed at the bracket150 accordingly. As can be seen, the position of the fixing element 160is not particularly limited in the invention. The aforementioned effectsmay be achieved as long as the fixing element 160 may be fixed at one ofthe torsion element 140 and the bracket 150 by the fixing portion 164.

In addition, according to the embodiments of FIG. 4 to FIG. 6, thetorsion element 140, the bracket 150 and the fixing element 160 arearranged adjacent to each other, and the first through portion 142, thesecond through portion 152 and the third through portion 162 are furtherdisposed at the shaft 170 by abutting each other. However, in otherembodiments not shown, other required members like elastic pieces orgaskets may also be disposed between the torsion element 140, thebracket 150 and the fixing element 160. The required members likeelastic pieces or gaskets may be sleeved on the shaft 170, and locatedbetween any two of the torsion element 140, the bracket 150 and thefixing element 160 or located outside of any one of the torsion element140, the bracket 150 and the fixing element 160. In those cases, thetorsion element 140, the bracket 150 and the fixing element 160 arrangedadjacent to each other are not limited to be abutted together. As can beseen, the specific composition of the hinge portions 130, 130 c and 130d of the hinge assembly 120 may be adjusted as needed, and the inventionis not limited thereto.

With the above arrangement, in the case where the fixing element 160 isfixed at the torsion element 140, when the torsion element 140 rotatesin relative to the shaft 170, the torsion element 140 drives the fixingelement 160 to rotate together. Alternatively, in the case where thefixing element 160 is fixed at the bracket 150, when the bracket 150rotates in relative to the shaft 170, the bracket 150 drives the fixingelement 160 to rotate together. In this way, while one of the torsionelement 140 and the bracket 150 rotates in relative to another one ofthe torsion element 140 and the bracket 150 through the shaft 170 as theaxle center, one of the torsion element 140 and the bracket 150 that isfixed with the fixing element 160 further drives the fixing element 160to rotate together. Therefore, wobble generated when the torsion element140 and the bracket 150 are in relative rotation may be reduced. Whenaforementioned arrangement is adopted in the hinge structure 100 adoptedby the electronic device 50, since the wobble generated when the torsionelement 140 and the bracket 150 are in relative rotation may be reduced,the operation of changing the two bodies 52 and 54 between the closedmode (the two bodies 52 and 54 are folded into one) and the open mode(the two bodies 52 and 54 are unfold to be separated from each other)may become more stable.

FIG. 7A to FIG. 7C are perspective side views of a hinge structureadopted by the electronic device of FIG. 1 in different operatingstatus. With reference to FIG. 1 and FIG. 7A to FIG. 7C, since each ofthe hinge assemblies 120 of the embodiment further includes three hingeportions 130 in which two of the three hinge portions 130 (e.g., thehinge portions 130 at the left and the right sides in FIG. 2) correspondto the body 52 (the corresponding portions are shown in dashed lines inFIG. 1) and one of the three hinge portions 130 (e.g., the hinge portion130 at the middle in FIG. 2) corresponds to the body 54 (thecorresponding portion is shown in dashed lines in FIG. 1), an upper oneof the hinge portion 130 in FIG. 7A is illustrated to represent thehinge portions 130 corresponding to the body 52 (e.g., the hingeportions 130 at the left and the right sides in FIG. 2) and a lower oneof the hinge portion 130 in FIG. 7A is illustrated to represent thehinge portion 130 corresponding to the body 54 (e.g., the hinge portion130 at the middle in FIG. 2), but the invention is not limited thereto.

In detail, the one of the upper hinge portion 130 and the lower one ofthe hinge portion 130 are connected with the same hinge cover 110 withtheir torsion element 140 respectively. When one of the two bodies 52and 54 rotates in relative to another one of the two bodies 52 and 54,such as the body 52 rotates in relative to the body 54, the upper one ofthe hinge portion 130 is firstly rotated with the body 52 such that thebracket 150 of the upper one of the hinge portion 130 is rotated inrelative to the hinge cover 110 and the lower one of the hinge portion130, as shown by FIG. 7A and FIG. 7B, and until passing through apredetermined angle (such as 90 degree), the upper one of the hingeportion 130 further brings the hinge cover 110 to rotate together suchthat the bracket 150 of the upper one of the hinge portion 130 and thehinge cover 110 are rotated in relative to the lower one of the hingeportion 130 (which can be considered that the lower hinge portion 130 isrotated in relative to the hinge cover 110), as shown by FIG. 7B andFIG. 7C, and vice versa. As such, during one of the two bodies 52 and 54rotates in relative to another one of the two bodies 52 and 54, only oneside of the hinge portions 130 is/are rotated in relative to the hingecover 110 while another side of the hinge portions 130 can be consideredas being positioned at a fixed position with the hinge cover 110.Thereby the hinge structure and the electronic device can providefavorable operating stability.

In summary, the hinge structure of the invention is disposed with thefixing element, wherein the fixing element is further fixed at one ofthe torsion element and the bracket (e.g., fixed by disposing theengaging portion for engaging the fixing portion of the fixing elementat one of the torsion element and the bracket), and the fixing elementmay be in form of one or more fixing plates or the fixing block.Accordingly, in the case where the hinge structure is used forconnecting the two bodies in the electronic device, when one of the twobodies disposed with the bracket rotates in relative to another one ofthe two bodies, one of the torsion element and the bracket is adapted torotate with the fixing element in relative to another one the torsionelement and the bracket with the shaft as the axle center. Therefore,wobble generated when said one of the torsion element and the bracketrotates in relative to another one may be reduced. As a result, thehinge structure and the electronic device of the invention can providefavorable operating stability.
